I, too, have questions:
I have seen advertised a bike-tire-filling aerosol substance that turns
into a foam inside the tire after being squirted in thru the valve.
Anybody used this? It is supposed to eliminate flats forever. If you
use this, can you get the tire off the rim ever again?
(Since you can't deflate the inner tube as much, physically, even if you
depressurize it.)

Another question: The advantage of pneumatic tires is the shock
absorbency of the air-filled cushion. Since bike tire pressures
for better bikes with thin tires are so high, is this effect largely
eliminated? If so, why not use solid rubber tires? (Or is heat
dissipation a factor here -- would solid tires melt?)
